Portable multimedia playback apparatus

Abstract

A portable multimedia playback apparatus is provided. The portable multimedia playback apparatus comprises a first video processing unit, a second video processing unit, a third video processing unit, a multiplexer, and a digital-to-analog converter (DAC). The first video processing unit generates a digital video signal. The second video processing unit processes the digital video signal to generate a TV compatible signal. The third video processing unit processes the digital video signal to generate a flat panel compatible signal. The multiplexer selects one of the TV compatible signal and the flat panel compatible signal. The DAC outputs an analog video signal after converting the selected signal.

1. A portable multimedia playback apparatus, comprising:
 a first video processing unit comprising:
 a pixel processing unit capable of generating a digital video signal and; 
 a flat panel processing unit capable of generating a flat panel compatible signal; 
 
 a second video processing unit comprising a TV encoder capable of receiving and processing the digital video signal to convert to a TV compatible signal; and 
 a DAC capable of outputting an analog video signal corresponding to one of the TV compatible signal and the flat panel compatible signal at a common output pin after converting the one of the TV compatible signal and the flat panel compatible signal into a corresponding analog form. 
 
     
     
       2. The portable multimedia playback apparatus as claimed in  claim 1 , wherein the TV compatible signal is a YPbPr signal. 
     
     
       3. The portable multimedia playback apparatus as claimed in  claim 1 , wherein the TV compatible signal is an RGB signal. 
     
     
       4. The portable multimedia playback apparatus as claimed in  claim 1 , wherein the flat panel compatible signal is an RGB signal. 
     
     
       5. The portable multimedia playback apparatus as claimed in  claim 1 , wherein the portable multimedia playback apparatus is a PDA. 
     
     
       6. The portable multimedia playback apparatus as claimed in  claim 1 , wherein the portable multimedia playback apparatus is a DVD player. 
     
     
       7. The portable multimedia playback apparatus as claimed in  claim 1 , further comprising a multiplexer capable of selecting one of the TV compatible signal and the flat panel compatible signal, wherein the DAC is capable of outputting the analog video signal after converting the selected signal.
